It would also seem to me to be an issue of what you are gluing together.
Around here we have welders with up to 500 amp capacity, and one with a 100% duty cyle at 800 amps. But how often are they turned up that far? Almost never. Only when we air/arc somthing.
So if all you are doing is light duty stuff, this might not be the issue you think it is. Welders are rated for their max output, turn em down and you would be suprised at how little they draw.
